Application - This Roush Quad Tip Active Axle-Back Exhaust System is designed to fit fastback or convertible 2015-2016 GT Mustangs.

ROUSH Active Exhaust System - Take total control of the volume and performance of your S550 GT Mustang with a ROUSH Active Exhaust system. Roush's proprietary Active Exhaust system ties directly into your Mustang's powertrain control module, opening and closing the mufflers valving based on throttle position.

Four Distinct Exhaust Sounds - The ROUSH Active Exhaust System includes a center console mounted selector knob that allows you to easily switch between four different sound modes on the fly. Choose from Touring, Sport, Track, and Custom.

Sport. The Sport mode keeps the exhaust quiet during normal driving conditions. Accelerator position and vehicle speed are used to determine valve position, opening up under acceleration for a more aggressive sounding ride.

Track. The Track mode is wide-open. This mode keeps the exhaust tailpipe valves fully open at all times and doesn't restrict the raw sound of your Mustang. This mode is intended for track use and is not legal for street use.

Custom. The Custom mode lets you create a custom sound map with the included WiFi OBD2 interface and ROUSH iOS application to personalize the exhaust sound to your own tastes. With the app you gain full control over the position of the valves based on vehicle speed, rpm and accelerator position.

Quality Roush Construction - Constructed from fully mandrel-bent 304 stainless steel for a durability, corrosion resistance and long life, the Roush Axle-Back Exhaust features two unique open chambered mufflers with 304 stainless steel dual wall quad tips. The 4" quad tips are finished with a new chrome flashing process that is resistant to discoloration due to exhaust heat.

Cut & Clamp Installation - The installation of this Axle-Back Exhaust requires cutting, removing the factory muffler assemblies and clamping the new muffler assemblies in place. Clamps, hardware and installation instructions are provided.
